Custom Engineering Capability

Every cable can be tailored in conductor structure, insulation system, shielding, armouring, and jacket design to meet 

specific electrical, mechanical, and environmental requirements.

With over 1,000 cable variants developed, our engineering team works closely with customers to create cable designs 

based on their application conditions, installation methods, and system requirements.

From conductor configuration and electrical performance to mechanical protection and environmental resistance, we 

provide customized cable solutions designed for each customer's specific operating environment.

Materials & Design Approach

Our cables are engineered using advanced materials including PUR, PVC, PTFE, FEP, PFA, PVDF, SILICONE, XLPE, and 

LSZH.

We select high-performance materials from trusted suppliers, including DuPont and Dow, to achieve excellent abrasion 

resistance, low-temperature flexibility, chemical resistance, and long service life.

Each cable design is optimized for specific operating conditions, ensuring reliable performance in demanding industrial 

environments.
